Abstract
The hard alloy product with complicated inner cavity is produced through common compression molding process, and may be also used in producing other powder metallurgical product.
Description
What the present invention relates to is the manufacturing technology of cemented carbide parts (pressed compact).
Usually the carbide alloy that adopts is molded into the shape method, get core difficulty and be difficult to obtain having the cemented carbide parts of complicated inner cavity by what, and the existing common method that is used to make the cemented carbide parts with complicated inner cavity, as the processing of plasticity blank, slip-casting, flexible die forming, etc. methods such as quiet hot pressing, then because of difficulty formation batch process or technology, equipment make its application be subjected to certain limitation than reasons such as complexity and cost height.
The method that the present invention proposes is to implement on the basis of common die forming method, during the compacting blank, with one give make earlier can bear pressing pressure and being dissolved in the pressed compact by the core package of certain dissolution with solvents, thereby the back that is shaped obtains the molten mistake of core to have the pressed compact of complicated inner cavity with solvent, certainly in whole technical process, core material that is adopted and solvent material should not produce adverse effect to alloy property.
Implementation method is given an example:
Accompanying drawing 1 is depicted as the carbide alloy blank of making binder with rubber.
Core shown in the accompanying drawing 2 adopts the urea after the 140C fusing to pour into a mould in steel die and cool off and make.
After suppressing the unitary blank that is inclusive with core by common mould pressing method, blank is put into alcohol (or clear water) with the molten mistake of core, put into drying box afterwards and be warming up to the 110C heat preservation and dryness, finished product is implemented and finally obtained to dried each operation according to common hard alloy production process.
Obviously, the method that the present invention proposes is suitably adjusted core and solvent material, the manufacture process of the complex-shaped blank of other powder metallurgy product of also available what except that carbide alloy.
Claims (2)
1, adopt to contain in the soluble core what pressed compact, thereby then core is obtained having the method for the blank of complicated inner cavity with solvent stripping from pressed compact, make cemented carbide parts.
2, adopt said method to make the sintered metal product of other kind.
